this case statement does not return the result i'm expecting

the value of wq.quantity_on_hand = 156, im.last_repack_item = 0, im.freight_item = .38010

( Case when im.last_repack_item = 0 
    then
        wq.quantity_on_hand * ( im.last_repack_item + im.freight_item ) 
    else
        0
  END ) repack_cost,

the select returns 59.2956 (156 * .38010) i thought it should return 0

i've worked around it by creating multiple columns, but i'd like to know if it's a bug, or if it's the way it's supposed to work.

thanks Tom M.

Why would you expect the expression to return 0?

The expression 'im.last_repack_item = 0' evaluates to TRUE since you tell us that last_repack_item is zero, so the value of the 'then' clause is returned.
